Senior FullStack Engineer

We’re looking for a Senior Full Stack Engineer to join our team at Astrix Security. At Astrix, we build cutting-edge cybersecurity solutions with a strong culture of ownership. We move fast, care deeply about quality, and expect engineers to use modern AI development tools (and structured AI workflows) to accelerate delivery - while keeping our code secure, maintainable, and reliable.

Requirements: 6+ years of full stack experience (or equivalent impact), with technologies such as TypeScript, React, Node.js, GraphQL, and SQL. Proven ability to take full ownership of projects - planning, execution, testing, deployment, and post-release improvements. Strong front-end fundamentals: component-based architecture, state management, responsive design, and performance. Strong backend fundamentals: API design, data modeling, scalability, and secure coding practices. Hands-on experience with AI-enabled developer tooling and workflows, including tools like Cursor, Claude Code, and Lovable, plus familiarity with using MCPs to bring relevant context into development safely. Ability to build structured, repeatable workflows using artifacts like rules, commands, skills, and MD files - and to teach others how to use them. Strong problem-solving skills, clear communication, and ability to thrive in a fast-paced, collaborative environment. Bonus: AWS experience (Lambda, S3, EC2) and experience designing scalable, secure cloud services.
